Placido is a cold, unloving android with a determination to kill Yusei Fudo. He is part of the tenor trio along with Lucciano and Jose, and thus wields his own Machine Emperor, Wisel. Through out his appearances, he is the most hands-on of the trio, to the point of assaulting Yusei(and by farther extent Dark Glass) himself. Unlike Lucciano and Jose who await the circuit to be completed the way it's suppose to be, Placido wants to straight out kill Yusei and force the circuit into completion.
